Arrange the following compounds in increasing order of dipole moment.

CH3CH2CH3, CH3CH2NH2, CH3CH2OH


CH3CH2CH3 < CH3CH2NH2 < CH3CH2OH

We know that nitrogen atom is less electronegative than oxygen atom. Thus, dipole moment of CH3CH2OH is greater than that of CH3CH2NH2. CH3CH2CH3 has the least dipole moment among the three given compounds because it is almost a non-polar molecule. Thus, the increasing order of dipole moment is CH3CH2CH3 < CH3CH2NH2 < CH3CH2OH.
